Chemical Information
FooDB NameAllantoin
DescriptionAllantoin, also known as glyoxyldiureide or 5-ureidohydantoin, belongs to the class of organic compounds known as imidazoles. Imidazoles are compounds containing an imidazole ring, which is an aromatic five-member ring with two nitrogen atoms at positions 1 and 3, and three carbon atoms. An imidazolidine-2,4-dione that is 5-aminohydantoin in which a carbamoyl group is attached to the exocyclic nitrogen. Allantoin is an extremely weak basic (essentially neutral) compound (based on its pKa). Allantoin exists in all living species, ranging from bacteria to humans. Outside of the human body, Allantoin is found, on average, in the highest concentration within milk (cow) and borages. Allantoin has also been detected, but not quantified in, several different foods, such as sour cherries, italian sweet red peppers, longans, sweet bay, and lambsquarters. This could make allantoin a potential biomarker for the consumption of these foods. Allantoin is a potentially toxic compound.
